    The instrument also performs a background gas measurement which serves as a reference measurement. The SmartDGA system collects the results of each gas analysis cycle and stores the data in memory within the SmartDGA EZHub controller.

    EZHub. The software can be installed on a Windows based PC or on the optional LumaSmart iCore device. The software also displays results and other data from the EZHub and SmartDGA instrument. This allows the user to track the dissolved gas as parts per million (ppm) levels over time and monitor gas levels against user defined warning, caution, and alarm settings.

    (Guide/Guard). Your EZHub may only be configured with an LTC or a transformer side, depending on your setup. The SmartDGA EZHub unit is the central node for the SmartDGA system. A fully configured EZHub is capable of handling the power and communication needs of a pair of SmartDGA instruments, either one Guard or one Guide in combination with an individual LTC (Gauge) simultaneously.

    IR filter and detector. There is an IR filter/detector pair for each gas to be measured. The detectors in the SmartDGA instrument are thermopiles. The filters are each designed to be band pass filters with the band being at a wavelength the gas of interest absorbs.

  • Page 15: Other Gas Measurements

    2.2.2 Other Gas Measurements The SmartDGA utilizes various independent sensors and calculations to measure Oxygen (O Hydrogen (H ), Moisture, and Nitrogen (N ).

  • Page 16: Oil-Gas Separating Membrane

    There is a metal plate with a grid of holes on the side of the membrane to add further support. At the beginning of each SmartDGA measurement cycle, a flow-controlled pump refreshes an internal reservoir with oil from the transformer/LTC system. During gas collection, the same pump is used to continuously replenish oil at the surface of the oil-gas separation membrane to expedite gas transfer.
